The drainage is normal, and it is no problem to manually drain once a month.
The role of the gas storage tank in the air compression system is: buffering, making the gas supply more stable and reducing the frequent start of the air compressor. At the same time, it is more conducive to dewatering and decontaminating the compressed air in the gas storage tank.
The basic requirements for gas tank selection are as follows:
1. The volume of the gas storage tank should be between 10% and 20% of the displacement of the compressor. We generally choose 15%. When the gas consumption is large, the volume of the gas storage tank should be appropriately increased. When the amount of gas used on site is small, it may be less than 15%, preferably not less than 10%.
2. The processing capacity of the dryer and filter should be consistent with the displacement of the compressor.
3. The filter before the dryer should be equipped with a electric auto drain valve.
4. When using the adsorption dryer, the compressor should reserve the corresponding gas consumption.
